2a + 3 - 9b - a - 7 Bring like terms together: = 2a - a - 9b + 3 - 7 Combine like terms: = a - 9b - 4
9b + 6 - 8 = -36 9b = -38 b = 4.2222222(repeating)
The simplified expression is -9a -9b.
(12a+9b)(12a-9b)
You would factor 3a + 9b as: 3(a+3b)
(27a)2 = 729a2 (9b)3 = 729b3 So (27a)2 + (9b)3 = 729*(a2 + b3)
9b2b is the base.==========9 is the coefficient of the variable term.2 is the exponent.
The common term for raising a base to the second power is to square it.Base^2
6 is the base number.
Since 3b is a factor of 9b, it is automatically the GCF.
3A + 9B = 3(A + 3B)
9
2a + 3 - 9b - a - 7 Bring like terms together: = 2a - a - 9b + 3 - 7 Combine like terms: = a - 9b - 4
9b + 6 - 8 = -36 9b = -38 b = 4.2222222(repeating)
The simplified expression is -9a -9b.
(12a+9b)(12a-9b)
the length of the base would be 16
